The communion of senses operates in the human being. Attempts to cross borders have been made for a long time and in different directions, and the contributions can be very enriching. Architecture, like music, is an unavoidable art. We live or share spaces created by the human hand. Friedrich von Schelling referred to architecture as frozen music, Goethe defined it as petrified music, and Gerardo Diego described music as sound architecture. There are many paths shared between the architect and the musician. Terminology is one of them. Architects talk to us about rhythm and harmonies, while musicians do the same about soundscapes and chromaticisms. The coincidences do not end with terminology. There are many other ways of integrating music and architecture. Spaces, forms, functionality, or delight are other aspects shared by musicians and architects.
